AISI 4140 low alloy steel containing Chromium and Molybdenum is the most widely used alloy for oil patch applications. Usually supplied in the hardened and tempered condition at 22 HRC max. it also finds favour in many applications requiring higher strength levels up to 150 KSI 0.2% PS. The grade is not NACE MR0175 approved in these conditions, and should not be used in environments containing H2S.
It is extensively used in tubular form for downhole tools.
Several hybrid analysis are available all based on the AISI chemistry. The most common change is to increase the Molybdenum level at 35% max on diameters, typically greater than 6″. Increasing Molybdenum improves the hardenability.

ASTM A182 is a martensitic stainless steel. The additions of Nickel and Molybdenum, which gives it excellent sub zero notch ductility, superior to other standard 13 Cr, 410 and 420 Mod martensitic stainless steels.
UNS S41500 steel is air hardening, with little danger of thick sections cracking during heat treatment.
In addition to limiting the maximum hardness allowed to 23 HRC max, NACE MR0175 imposes heat treatment temperature restrictions.
The weldability and corrosion resistance of ASTM A182 are also excellent, being extensively used in the manufacture of Valve Bodies, Flanges, Seats, Gates, and Tubulars.
ASTM A182 specifies a minimum 0.2 PS value of 95 KSI. This NACE approved grade is limited to 75 KSI because of the hardness restriction.

17-4 PH is a precipitation hardening martensitic stainless steel, containing Copper. In the solution treated and doubled aged condition it has become the preferred alloy for Stems and Shafts and is used extensively in valve internals. High strength, including good properties up to 315°C (600°F) and excellent corrosion resistance (comparable to 304 austenitic stainless in many environments) makes this alloy extremely versatile.
In addition to limiting the hardness, NACE MR0175 restricts the age hardening cycles that can be applied to the alloy to two of the several available. NACE MR0175 only permits solution treatment, followed by double aging to either the H1150M condition 760°C (1400°F) / 620°C (1150°F) or the DH1150 condition 620°C (1150 °F) / 620°C (1150°F).
ASTM A564 lists several alternative supply conditions.
Until 2003 this alloy was approved by NACE MR0175 for general use. However, it is now restricted to “special components” and restricted well environments.

Stocked through a wide range of sizes, in either mechanical tube, casing or DOM (drawn over mandrel) product forms.
These grades of low alloy steel containing Chromium and Molybdenum are the most widely used alloy for oil patch applications. Usually supplied in the hardened and tempered condition at 22 HRC max. They also find favour in many applications requiring higher strength levels up to 150 KSI 0.2% PS. The grade is not NACE MR0175 approved in these conditions, and should not be used in environments containing H2S.
The hardenability limitations of this grade (depth to which it will harden / obtain the specified mechanical properties after heat treatment) must always be taken into account when designing and selecting equipment.

This is a nickel-chromium-iron alloy with additions of molybdenum and copper. Some of the minor elements are controlled to yield increased resistance to heat-affected zone (HAZ) corrosion and improved weldability. Alloy G-3 has excellent corrosion resistance to oxidising chemicals and atmospheres. It is also resistant to reducing chemicals because of its nickel and copper contents.
Nickel also provides the alloy with exceptional stress-corrosion-cracking resistance in chloride-containing environments. The high molybdenum provides very good resistance to pitting and crevice corrosion. The low carbon helps prevent sensitization, giving the alloy resistance to intergranular corrosion.
Today’s exploration for oil and gas leads to a range of highly corrosive environments that, in turn, require a range of corrosion-resistant high nickel content alloys. Alloy G-3 is one of these alloys, providing an excellent combination of mechanical properties and strength. This alloy has been used extensively as OCTG in hot, sour environments.
